- Screening Air Dispersion Model for Aermod



AERSCREEN View is a user friendly interface for the US EPA AERSCREEN screening-level air quality model and associated modeling programs. AERSCREEN estimates worst-case impacts of ground level concentrations for a single source by interfacing with the screening mode of the AERMOD model. Scenarios can include simple or complex terrain, building downwash, and NO2 chemistry.


With AERSCREEN View, users can perform simultaneous model runs for a variety of source types and scenarios. The Scenario Wizard makes it easy to create and manage inputs for different model inputs. The program also contains many attractive display options for model output including text, graphical, and tabular formats. Preliminary modeling with AERSCREEN View can remove the need for more complicated modeling, saving you time, and resources.


Integrated Graphical User Interface

Fully integrated interface combining easy to use graphical tools (e.g., sources, buildings), model run batcher, and advanced output display.


Scenario Wizard

Allows you to quickly and easily set up modeling scenarios in AERSCREEN View. Data blocks are intuitively grouped for simple data entry. Incorporate downwash, terrain effects, meteorological options, and more with ease.


Data Tree Display

AERSCREEN View stores all scenarios in a convenient data tree display for easy access. You can create new scenarios, copy existing ones, and quickly analyze multiple output files with the click of a mouse.


New Project Wizard

The New Project Wizard allows you to quickly and easily set up a new project in AERSCREEN View. You can import from an existing AERSCREEN input file or set up a brand new project by specifying a reference point in Latitude/Longitude, UTM, or any other local coordinate system.


Terrain Processor with Automatic Downloads

Advanced terrain processing capabilities are offered for several terrain data file formats such as NED, SRTM, and USGS DEM. Automated download of terrain data files from webGIS. SRTM3 terrain data at 90 m resolution is available worldwide.


Advanced Output Viewer

Review output from each scenario as text output files, tabular concentration data, and fully-customizable output graphics are available for you to analyze and interpret.


Model Run Batcher

AERSCREEN View automatically creates and processes input files via the Model Run Batcher. With AERSCREEN View, you can run multiple scenarios simultaneously saving you valuable time.


Seamless Model Integration

AERSCREEN View includes all of the Fortran programs necessary to complete your analysis: BPIP (building downwash), AERMAP (terrain processing), MAKEMET (meteorology data), and AERMOD (dispersion analysis).
